Armorblox + Microsoft: Better Together
Built to Augment Native Microsoft Security
Our platform is built to stop targeted email attacks that slip past Microsoft security controls -- without duplicating existing Microsoft capabilities.
Connected with Azure Sentinel
Save time on security operations by routing threats detected by Armorblox to your Azure Sentinel environment.
Strong Microsoft Partner
Armorblox is available on the Microsoft Azure Marketplace with purchases counting towards enterprise Azure commitments. Armorblox is also a member of the Microsoft Intelligent Security Association.
Your Post-Microsoft Protection Layer
Armorblox connects over APIs and analyzes emails after Exchange Online Protection and Microsoft Defender.
A Secure Email Gateway (SEG) solution will require that you turn off native Microsoft protection. Armorblox works in tandem with Microsoft instead.
Armorblox analyzes thousands of signals to stop:
Socially engineered attacks
Advanced phishing
Third-party attacks
Account takeover
… and other attacks that get past Microsoft security controls.

How It Works
Armorblox secures the human layer by understanding the context of your organization, your users, and your communications.
Connect
Connects over API in 5 minutes without any MX record modifications or email rerouting.
Train
Analyzes 6 months of email archives and builds communication baselines for your organization.
Protect
Flags targeted email attacks and data loss violations automatically - no policy setup needed.
Respond
Automated and configurable remediation actions: delete, quarantine, employ warning banners, lock accounts.
Learn
Learns from every threat, manual action, and false positive to get better with time.
Built to Catch Attacks That Get Past Microsoft
Microsoft security controls are effective at stopping spam, known malware, and phishing - so effective that organizations are discontinuing their SEG investment.
However, many targeted email attacks like Business Email Compromise and spear phishing still get past Microsoft security controls.
Armorblox is built to learn from every customer’s data and stop advanced threats that cannot be caught by filters, blocklists, and other binary detection techniques.
